Fetal Development in the Fourth Month

A fourth month of pregnancy is an exciting stage when the development of the fetus becomes more visible, and the mother increasingly perceives the baby’s movements. During this time, the baby’s bones begin to harden, and the movements become more active. Although the fetus is still small, the continuous movement makes it increasingly noticeable for the mother that the baby is kicking.

The baby’s development in the fourth month

In the fourth month, the development of the fetus is striking. By this time, the baby already knows that it can put its finger in its mouth, and the tooth buds also begin to form. Mothers typically feel the first movements of the fetus around the 18th to 20th week, while those expecting their second or more children may experience this earlier. Fathers can also join in the experience, as the baby’s kicks become perceptible through the abdominal wall.

The external genitalia of the fetus also undergoes development, allowing experienced ultrasound technicians to determine the baby’s gender. This stage of development is exciting, as the pregnancy becomes increasingly concrete for the parents, and the baby’s personality begins to unfold.

The mother’s body in the fourth month

Significant changes can also be observed in the mother’s body during the fourth month. The belly becomes rounder, and for many women, it is time to purchase their first maternity clothes. During this month, previous nausea is likely to subside, replaced by feelings of cravings. It is important for the mother to pay attention to her nutrition and consume desired foods in moderation, avoiding empty calories.

Movement is also extremely beneficial during this time. Light exercises, such as prenatal yoga, swimming, or long walks, have a positive effect on well-being for expectant mothers. Additionally, many pregnant women experience increased sensitivity of the nipples, and the veins in the breast skin may become visible, which is also a natural part of pregnancy.

Pregnancy examinations in the fourth month

In the fourth month, during the 16th week, an AFP screening is performed, which is simply a blood test for the mother. This examination is particularly important in terms of timing, as early or late testing can yield different, even erroneous results. The AFP test provides information about the risks of neural tube defects and Down syndrome.

It is important to note that neither a high nor a low AFP level necessarily indicates fetal disease. If discrepancies arise, targeted ultrasound examinations will be conducted, or if necessary, further genetic tests may be performed by specialists. Therefore, it is crucial for the mother to participate in the necessary examinations, as these can contribute to the preservation of the baby’s health.
